Regarding 1.
There are many opportunities for an edit operation to fail: Attribute rules, relationships, domain values, etc. I would suggest you start your debugging session with as simple as possible (i.e. only add an item with the geometry set) and if that works you can add more fields to find out when it fails. If the simple case doesn't work your geometry might be bad, or there are domain value requirements with no default values, or other attribute rules. Without code and data sample i can't help.
Regarding 2:
I am still not 100% sure what you're trying to accomplish, but i think you want to maintain the current feature selection (from the map) and only customize the row selection (from a table) that is done via your custom UI. If that's the case, then the solution i listed above will do the job as it doesn't affect any existing feature selection.
// load the first selected feature into the inspector using the first OID from the list of object IDs
var mapMember = firstSelectionSet.Key;
var oid = firstSelectionSet.Value[0];
inspector.Load(mapMember, oid);
//Create new feature from an existing inspector (copying the feature)
var createOp = new EditOperation
{
Name = "Copy first selected row",
SelectNewFeatures = false
};
var rowToken = createOp.Create(inspector.MapMember, inspector); // inspector.ToDictionary(a => a.FieldName, a => a.CurrentValue)
if (createOp.IsEmpty)
{
MessageBox.Show($@"Record oid: {oid} in table: [{mapMember.Name}] was not duplicated");
}
else
{
var result = createOp.Execute(); //Execute and ExecuteAsync will return true if the operation was successful and false if not
if (!result)
MessageBox.Show($@"Copying record oid: {oid} in table: [{mapMember.Name}] failed: [{createOp.ErrorMessage}]");
else
{
var newOid = rowToken.ObjectID.Value;
MessageBox.Show($@"New record oid: {newOid} in table: [{mapMember.Name}]");
// now add this record to the existing selection
(mapMember as StandaloneTable).Select(new QueryFilter() { ObjectIDs = new long[] { newOid } }, SelectionCombinationMethod.Add);
}
}
The key to get the NEW row into the selection are these lines:
1. "SelectNewFeatures = false"
2. "(mapMember as StandaloneTable).Select(new QueryFilter() { ObjectIDs = new long[] { newOid } }, SelectionCombinationMethod.Add);"
Now as the code says this will add the new row to the existing selected rows of my custom UI code, if i want to remove any old rows i can simply call:
"(mapMember as StandaloneTable).Select(new QueryFilter() { ObjectIDs = new long[] { oldOid } }, SelectionCombinationMethod.Subtract)
Or if you want to clear all records for the table that are selected in your custom UI before you make a new selection you can simply call the following before the new selection code is executed:
"(mapMember as StandaloneTable).ClearSelection()"
You cannot control which row is hightlighted in the Attribute tree view (the highlighted row is used for detail display).
